Sad welcome and I'm sorry you're here. I suggest that you start to go to an individual counselor for YOU. As difficult as it is right now you need to remain calm and remember that this is a marathon not a sprint. As far as not liking being in the house, IMHO you should stay. Your W is the one who wants out at this point and as such you could tell her calmly that you will not leave your house. I decided myself to do this with my W and she did not like it but she now is leaving at the end of this month. It's my belief that when a WAS wants out and still wants to remain in the house that they are cake eating. Some on the boards may not agree with me. Post often. I'll check in later I'm pressed for time.
